Sample script to build ZIP-files with LZMA-compressed entries

Any entry in a ZIP-file, that was compressed using LZMA, can be listed, but cannot be extracted. This is true for both unzip(1) and tar:

    unzip: lzma unknown error 1

and

    x core.26303.txt: lzma unknown error 1
    tar: Error exit delayed from previous errors.

Unzip installed by archivers/unzip cannot handle such entries either, but 7za can.

Both tar and unzip already link with liblzma, so it should be working, but does not -- and with the same message. Which suggests, the problem is with libarchive...

Attaching a Python-script, with which such ZIP-files can be created:

    ./ziplzma.py foo.zip file1 file2 ...

Reproduces on CURRENT.
Comment 2 Hans Christian Woithe 2020-02-08 13:59:14 UTC
I was also able to reproduce the problem.
It seems this was fixed in libarchive commit c8d40b27 issue #1257.

use the program above to create a test.zip file
$ echo "test" > test.txt
$ python3.6 ziplzma.py test.zip test.txt
$ rm test.txt

$ unzip -o test.zip
unzip: lzma unknown error 1

$ cd /tmp
$ git clone https://github.com/libarchive/libarchive.git
$ cd libarchive
$ git checkout c8d40b27
$ build/autogen.sh
$ ./configure
$ make

$ LD_PRELOAD="/tmp/libarchive/.libs/libarchive.so" unzip -o test.zip

This fix should be part of r356212.
So instead of the above procedure, you should be able make lib/archive and LD_PRELOAD the generated library.
In my testing environment that's currently in /usr/obj/...

$ LD_PRELOAD="/usr/obj/.../amd64.amd64/lib/libarchive/libarchive.so" unzip -o test.zip

Libarchive 3.4.2 will be merged to 12-STABLE, 11-STABLE and 10-STABLE in about 1 week.
